What is the correct behavior of a proxy that gets excessive headers from a server? What if the header stream takes too long, without being particularly large? Then the problem is not too many headers at all. Indeed, for a reverse proxy with a slow client, this is sure to happen as sure as streaming kicks in at all. I get the sense that HTTP/2 reverse proxies can’t use multiplexing upstream. Is anyone yet testing reverse proxies? > Receiving CONTINUATION forever is unrealistic situation. Receiving CONTINUATION even once is unusual, if not unrealistic. The frame size was reduced simply to generate more CONTINUATIONs, so just as easily they could be all but eliminated. Yet header-streaming protocols come up as a necessary future use case. If they are not nice to have and we don’t want to support them, then a line should be drawn and a limit set. Are there any uses *in practice on the public internet* for headers longer than 64K as serialized by HTTP/1.1?
